TEMPORARY Brianna.

Application filed January 30, 1926. Serial No. 84,892.

This invention relates toa loose-leaf binder of the type disclosed by my Patent No. 1,441,873, dated January 9, 1923, and comprising a base provided at'one edge portion with bearings and guiding slots, a Vplurality of leaf-engaging members including resilient arched portions and axle portions joined to the inner ends of the arched portions and journaled in said bearings, each arched portion extending through a guilding slot Vand having a notch adjacent its outer end, and a plurality of orifices in the base, each forming a detent adapted t-o be engaged by the notch of one of the arched portions, when thelatter is turned about the axis of its axle portion into operative position.

In said binder the bearings, the guiding slots, and the detent-forming orifices are formed in a sheet-metal member constituting an element of the base. The flexibility of said member, due to the inherent flexibility of the sheet met-al, and to the weakening thereof by the formation of the guiding slots and detent vorifices therein, is such that the member may be easily bent crosswise, and thus distorted from its predetermined and essential straight form. 1t is therefore 'necessary to lprovide vmeans for stiffening the sheet-metal member', and this is accomplished in the device of said patent, by stiffening means incorporated in the back of the cover, so that the complete binder necessarily includes a cover, the back of which is structurally stiffened.

T he chief object of the invention is to provide an improved base formed independently of the cover and including a sheet metal base member provided with the guiding slots'and detent orifices, and a'i'einforcing member cooperating with the sheet-metal member4 and in forming, in one edge portion of the base,

a cavity in which the axle portions are journaled, and, inthe opposite edge portion of the base, a cavity adapted to receive the notched endsl of the leaf-engaging members, the base l and leaf engaging members being adapted for attachment as a unit to the cover back, which is limp and iexible, so that the cover may include a back and sides formed f rom a single sheet of flexible material, as leather', paper, or cloth, the desired stiffness being provided wholly by the independently formed base. Another object is to provide a base characterized as above stated, in which the sheetmetal member bottoms the cavity receiving Figure 1 is an end elevation of an article constructed in accordance with the invention. l

Thesanie reference vcharacters indicate the saine parts in all of theligures.

vWhile 'the cover` may be of any suitable construction, l prefer to make it from a single flexible sheet of leather, paper, cloth,or other suitable` material including a back portion 12, and side portions 13. To the backis attached by rivets or other suitable fasteners le, an inherently Istiff base :formed independ-l ently of the back. Said base iscomposed of a relatively thick oblong reinforcing inember 15,- preferably of press board or binders board, and al sheet metal base member 16, superimposed onone side (hereinafter termed Vthe lower face) of the member 15 kand having hooked flanges extending acrossv the longitudinal edges ofthe reinforcing member and superimposed on the opposite side (hereinafter referred to as the upper face) thereof, each flange including a neck portion 17, and a flat portion 18. The edges of the reinforoing -member and the hooked flanges form, along one edge portion of the base, a longi- "ltudinal cavity 19,'in which the axle portions 20 of the'leaf-engaging members described bymy former patent, are journaled,.and,

fragmentary perspecalong the opposite edge portion of the base, a longitudinal cavity which may be vformed in part by notches or recesses 21, in the reinforcin'g member. The last-mentioned cavthrough and being guided by the walls of said` slots. The detent-forming orifices 24 are at the opposite edge portions of the base and preferably formed in the flat portion 18 of one of the hooked fianges, as shown by Figure, althoughthey may be formed in the body portion of the reinforcing member, as in the modification shown by Figure 9, and hereinafter described.

The general operation is the same as dei scribed in my former patent. lhen the notched ends of the arched portions 22, enter the detent orifices 24, their entrance is limited byl portions of the base member, as indicated by Figures 7 and 8, bottoming the cavity or cavities in which the notched ends are inserted, so that there is a sheet-metal barrier between the notched ends and the cover back, preventing indentation and wear of the back y by the notched ends.

It will now be seen that the improved base makes it possible to use flexible leather fabric or paper for the cover, without any stiff back portion being' incorporated within the cover.

It will also be Vseen that the reinforcing member serves a two-fold purpose: First, holding the wire members of the binder in place in the base, one edge of the reinforcing member forming part of the bearing for the axles of the wire portion; and second, supplying necessary support and strength to the sheet-,metal base member. This base member is so modified as compared with the form shown by my former patent, that vit bottoms the cavities receiving the swinging ends of the arched portions 22, and therefore furnishes in itself the necessary stop-s for said ends, thereby rendering further reinforcement of the back portion of the cover unnecessary. rlhe result is a stronger, stiffer binding element, complete in itself, adapted to be attached to any form of cover, flexible or otherwise. p

yTheimproved base is a further improvement on the former type, in that it presents a flat top surface on which to manipulate paper into or from the arches, as compared with the raised beading of the former type. This flat surface provides better articulation for the locking ends of the archesthan does the the detent orifices. The sheet metal base member is simpler to manufacture, requiring less complicated dies and fewer stamping operations.

The whole device is designed primarily to furnish a binder member complete in itself and of stronger construction than heretofore, which shall Vpermit the use of flexible cover material, without structural reinforcement of the back portion of the cover.

The notches or recesses 21 may be omitted, so that the entire edge forming one side of the cavity receiving the notched ends of Ythe arched portions, is straight'and offset inward, as indicated by Figure 11. It will be seen that with the notched form shown byFigures 4, 6, 71and 8, the edge portions of the reinforcing member, between the notches 21, support the flange containing the detent orifices 24, at opposite sides of said orifices, as indicated by Figure 8, while the form shown by Figure 11 avoids the necessity of exactly positioning the member 15 to cause notches in one of its edges to coincide with the detent orifices 24.

The base member' may be inverted from the position shown by Figures 1 to 8, so that the body portion thereof will bear on the outer side of the reinforcing member 15, asin the modification shown by Figure 9, the detent orifices 24 being formed in the body portion, instead of in one of the flanges. In this modification the reinforcing member may be attached to the'cover back by fasteners 14, the inverted sheet metal base member being then moved endwise to place on and into engagement with the reinforcing member, the flange portions 18 being interposed between the inner side of the reinforcing member and the cover back.

The body portion of the sheetmetal base member may be directly attached to the cover black, as indicated by Figure 10, the reinforcing member being then moved. endWise into engagement with the said base member.

I claim:

A temporary binder comprising a base including an elongated reinforcing member of substantially the full length of the base ,and a transversely bent sheet metal member extending entirely over one face of the reinforcing member, vacross the adjacent edges of the reinforcing'member, 'out of contact therewith, and onto the opposite lface of said reinforcing member throughout the length thereof, whereby the sheet metal member is stiffened throughout its length and provided with interior longitudinally extending cavities, the inner side walls of which are formed by the edges ofthe reinforcing member, a plurality of slots being provided in the outer side wall and top wall of one of said cavities and corresponding apertures, in substantial transverse alignment with said slots, being provided in the top wall of the other said cavity, a plurality of independent leaf engaging members each extending through `one llt) of said slots and having one end bent laterally into the communicating cavity to form an axle permitting the member to be bodily rocked to move the free end thereof into and from the cooperating aperture in the base, and a cover secured to the base against the opposite face thereof from that from Wliicli the leaf engaging members project, said base, reinforcing member and leaf engaging members constituting a unitary structure adapted 10 *f In testimony whereof I have afiXed my E5 signature.
